HOUSING FOR' HIGH-DENSITY CONSPRESSES. 7

Application filed July 20, 1925. ser al Ne. 44,860.

The present invention relates toipress'es and particularly to cotton presses ,ot the high density type, such as disclosed in Patent No. 828.002, issued August 7, 1906 to Samuel J. Webb. v

High density cotton presses such as disclosed in the patent just referred to comprise essentially upper. and lower main platens for eli'ecting the actual compression of the cotton and side plates for holding'the cotton fibers againstlateral displacement while such-compression is being flefiected.

bale andplacement of an uncompressed or plantation bale in the press are readily I efiected. The movement of theside plates,

- toggles mast withstand great pressure, as 1 will be evident, and hence the heel pins must v which are hinged about their lower edges, Ia

vfrom operative to inoperative position and vice versa, iseiieeted' by mechanism which includes a power operated toggle for each side plate, the upper [end or which is pivoted to the side ,plate' and the lower end of which is pivoted upon' aheel pin o rodsupported from the 'ira1ne: or.; housing of the press. 7While thepres is in operation, and compressing'a bale, the

be very substantially supported from the frame.

My invention relates to the; supporting mechanism for these heel pins, and itsobject is to providesuch mechanismwhieh is' of a rigid. construction forming a strong support, while at the same time permitting adjustment of its members so that the posivtions or the heel pin-s may be slightly modified or changed from time to time to insure the easy and proper adjustment of thetogglesthat moveithe side plates .or displacement plates of the press, permitting-adjustment for wear or parts, such as the toggle joints and'heel pinsand heelpi'n' bearings.

The invention is applicable to presses heretofore constructed for use as well as presses hereafter to be newly constructed, and, when applied to presses which have been heretofore manufactured and sold, greatly increases their effectiveness in operation and corporated therein c Figure 3 operative value, as well as greatly increasing the length of life.

.One form of the invention is illustrated in the accompanying drawings in which Figure 1 is a front elevation or a high density compress, showing the invention in- Figure '2 is a side elevation of the same;

and L I v p F igure4 1s a vertical section of a modification showing this detail integral with the housing.

The compress-in its entirety, with the eX-.

ceptionof the present improvement, is disc'lo-"edinthe prior patentto Samuel J. l/Vebb above mentioned, and will not be described 1n detail herein.

Briefly stated it is provided with a stationary upper platen'lO and movable lower platen, which is not percepti Jble in the views or the present application, a power piston in an elevated cylinder 11 for bringing these platens together and sepating them, and side plates or displacing plates '12, which are movable from the os'itio'ns in which they are indicated in t iill lines in Figure l to the positions in which [they are shown in dotted lines in the same figure by mechanism now to be described. Each displacement plate is provided with a toggle comprising a member 13' and a member 14 pivoted'tog'ether at 15, for operating the same. The inner end of each member or each toggle is'rounded and fits within a'fcylindrlcal groove or socket 1'6 in the corresponding displacement plate, and

the outer end of each toggle member 14 is journalled upon a heel pin '17.

7 Heel pins 1.7 areparallel toeach other and supported by tie rods from the housing of the compress, Thus parallel horizontal tie rods 18 secured by brackets or clamping members 19 are provided with apertured ends thru which the heel pins extend. These tie rods 18 hold-the heel pins against horizontal movement outwardly when pressure is exerted against the displacement plates 16.,

On each side of the machine are disposed Qtwo inclined tie r0ds'20, the lower ends of which are enlarged and aperturedzto receive the heel pins 17 and the upper ends of which lie in grooves 21 in brackets 22. These brackets may be either integral with the frame members 23 of the press, or formed separately and bolted thereto. In the preferred embodiment of the invention herein is a perspective View of a detail;

disclosed, these brackets are bolted to the frame members 23. In Figures 2, 3 and 4,

the details of the brackets are clearly dis-.

plate 29 which meets its back plate 30 at an frame of the compress.

angle of ninety degrees. Perpendicular webs 31, arranged at right angles to the back plate, connect the back and foot plates, and on one of these on each bracket is arranged the yoke member 32 having the groove 21 previously referred to. The upper surface 33 of this grooved member is disposed in a plane which is at right angles to the tie rod 20 when the structure is assembled and serves as'a seat for a ring or washer 34:

which encircles the upper end of each tie rod. Above the washers 3e are ad usting nuts 35 which are threaded upon the upper ends of the tie rods. By adjusting these nuts, it will be seen that the heel pins 17 may be drawn parallel or lowered or raised to a slight extent to secure the exact adjustment of the heel pins which may be desired. From time to time, in the operation of the machine, it will be desirable to effect these adjustments; and the construction just described also facilitates assembly of newly constructed presses.

In the form of the invention shown in Figure 4 the bracket is integral with the This is the construction preferable in the case of compresses hereafter to be constructed. Those already in use may be fitted with the improved bracket shown in Figures 1, 2 and 3.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. The combination with a high density compress having a housing, upper and lower platens, hinged side plates, and toggles for operating theside plates, of parallel heel pins for the toggles, and a frame for sup porting the heel pins so as to be vertically adjustable for the purpose set forth, said frame including inclined tie rods having rods.

their upper ends threaded andtheir lower ends engaging the heel pins, seating surfaces on the outer sides of the housing transverse to the tie rods respectively and nuts on the upper ends of said tie rods which bear each side of said housing, to receive the other ends of said tie rods, an abutment on each bracket, and means cooperating with each tie rod for transmitting pressure from said heel pin to said abutment, said means being adjustable to vary the length of said rod.

3. The combination with a high density compress having a housing and a pair of heel pins, of a pair of tie rods attached at one end to said heel pins, and a bracket on each side of said housing having a recess forming a seating surface for the other end of each tie rod, means on each tie rod for adjusting the' position of its associated heel pin, each of said recesses being open at its outer side to facilitate assembly, replacement and adjustment of said press.

4. The combination with the housing of, a

high density compress of brackets on the outer sides thereof provided with openings for thereception respectively of downwardly. and outwardly inclined tie rods, the brackets having inclined bearing surfaces constituting" seating surfaces for threaded upon the respective tie rods.

5. The combination set forth in claim 4:, in which the openings comprise grooves with their long axes downwardly and outwardly inclined and parallel to the respective tie 6. The combination with a high density compress having a housing, upper and lower platens, hinged side plates, andtoggles for operating the side plates, of parallel heel pins for the toggles, and a frame for 'sup porting the heel pinsso as to be vertically adjustable, said frame including inclined tie rods having their lower ends engaging the heel pins, means on saidhousing to receive the upper end of said tie rods, and means cooperating with said first named means for adjusting the length of said tie rods to take up wear in the operating parts, and preserve the operative position of said side plates.

In testimony whereof I hereunto affix my signature.
